You might consider rotating the PA deck 90 deg so the output transformers face down.

This way you will have nice short connections to the PA tank and it will be easier to hook up the driver with equal length cables (phase match) to each stage.

This might affect cooling though (not sure of you fin orientation).

Just a suggestion :p

Dave I have finished the tank circuit today...the fins are shown with longest length going vertical...the output is now directly attached to the tank with about 6 inches of number 6 THNN.
The only problem with this layout is I would have like to bring the output of the secondaries closer to the tank cicuit, but it won't matter much as everything is on a huge copper ground plane made up of copper roof flashing and everthing is strapped together.

I also have finished the driver...I will post some more pics tommorow.
Testing tommorow on the driver input circuit and the attaching to top of rack and connect to output of driver cicuit to gates of the rf deck and test again to make sure I have 24 volts pep of the gates.

Brent,
        Terrific job and am looking forward to hearing you on the air!

        Just a couple of questions: Where do the tube sockets go and I
        I didn't see the filament transformer.

        Am I missing something here?HuhHuhHuhHuh?

I would have finished talking to you today but I set another antenna on fire. Cheap swill cannot take AM. The rig went beserk, pinned the watt meter and pumped 1.2 gigawatts into the short. Rig is fine, antenna is toast.
